Beit known that I, lin-.vnr G. Frsrin, or' Springield, vin the county ot' Hampden, and State ot' Masf snchusetts, have inventcd certain new and useful Inn ploi'emeuts in Apparatus for Lighting Gas, which I denominate au Improved Gas-Lighter; and I do hereby declare that the following is a full, clear, and

exact description thereof, referen being had to the accompanying drawings, making a part of this speciilcation, and tothe letters of reference marked thereon,

My invention relates to the application and use of,"

electnrmagnetism, or electricity, or both, lin connec- -tiou with a gas-burner, for the purpose of admitting the. gas into and through the burner, and lighting the same; and

1t consists in the-construction, arrangement, and op ntion of a valve, gasfburner magnet, and other parts, whereby the gas may be turned on, or' be permitted to pass through and out of said burner, or any number of them, and lighted allat the same instant, nearly, and the whole controlled bycne person, stationed. at any distance from said burner-'or burners.

That others skilled in the nrt may be able ro make and use my invention, I will proceed to describe its construction and inode ol' operation.

In the drawings- B represents an ordinary piece of brass tube', or pipe, having a scrcwthread, B', out upon its lower nari, and also having a passage, y, therein.

At r, the passage y terminates in a shoulder, above -which the passage widens into the chamber o, which extends upward to the shoulder 2.

there this said shoulder s, the chamber is still more enlarged, and forms the armature-chamber A., which is within the cz'sse A2, at the upper part ol' which onse, and -upon the inside, is cut a female-screw thread. Y A

Apertures, A', are also made in said case A, one upon each side, and directly opposite each other.

l represents the valve'case, and is made of brass or other suitable metal, the lower portion being made somewhat larger-'than the upper part, and male-screw' threads f and g cut thereon, the thread g, on the lower portieri, litt-ing the thread cut upon the inside of the The lower portion of the piece, or case I has the chaudier- 1 therein, the upper' part h of which-is corr-lical, or in the form of atruncated cone, and forms'v the seat ofthe valve; and above the seat h, and cornmuiricuting with the chamber l, is the passage, or orilice f'.

Thennt H, which is of suitable thickness, Iis perfqated, and has a screw-thread outtherein, weich lits the screw-threaul g, upon the lower and larger' part of the piece I. l

AThe wireinsulator E is made of any suitable substance which isa non-conductor of electricity, of suitable thickness, and having' the perforation, or :Iperture t therein, through which is inserted, or protrudes the ripper' part ofthe valve-easel. A circular' portion is cut away, leaving an annular space, or channel t around the aperture t, into which' annular space the top oi' the large or lower partof the valve-case I protrudes, when it may be 'drawn upward by the adj usting-nut H.

The apertures s s are also made near each end of the insulator, into which pass the wires L L.

The Lerner-#insulator E' is cylindrical in form, with.

in the lower and larger part oi' which is a chamber, and a screw-thread is cut upon the inside oisaid insulator, which fits the screw-threzul f upon the upper and smaller part oi' the oase l andthe upper and smaller par rt of said insulator has a screw-tlrread made thereon, which ts the screw-thread made in thelowcr: part of the burner G, and a passage,'or orifice, z, extends from thechamber inthe said insulator upward, to the top of said insulator, aii'ordiug an unobstructed passage ot' gas through the insulator, when in opera.- tion.

By this method of insulating the burner and lighting-wires l), I nur enabled to use a single wire for the f purpose ol' lighting, which wire may be attached 'to' the insulator E', the Spark, or current ol electricity passing from the pon.' oi" said wire, through the gas, to the top ofthe burner, and from thence to the next insulated wire, by means of a wire attached to said burner I attacha wire, passing itbelow the insulator,

smoes 'between the lightingwires amounted to' r'noie than twice thedistance between'the lightinglwire and .'on through these wgr'egate spaces, andwould take of the nst burner, then pass through the pipe lo the and ii'oinfthenceback to the coil.

l and hghting-wirev b, as "herein described, remo\'es the script-ion.

Y valve, nearits p.

I convenient length, and having the aperture e' therein,

rlhis construction and arrangemenglessens the'cost of this apparatns, as compared with othersiunse, as it dispenses with one wire, 'and the size of the insu-v lator E canbe 1eduoed,iouly one insulator being required for both tlie wire 'b and' burner, while its opention is as certain as if two wires were used.

It is also immaterial what kind ofv burner is used,- as a. metallic tip is equally as operative as alava tip, and, indeed, I prefer to use a metallic burner.

By-insulatingthe burner in this manner, I am ens bled, in using any kindof burne,-'to".use"only` one wire fromithe coil .to the burners, and to the last and attaching it to thevpipe, connection beiug'inade at the other end of the pipe with the coil, so that 1 make the pipe serve as the retumwire ibi-'the greater part Aof the distance."

"If very many burners having lava tipsfwere to be lighted by electricity, and they aggregate distances or the metal portionoftheburner, past. .the'lava, the spark','or current would then probnbly-ieihse to-puss the shortest aggregate distance, or pass from the' lighting-wire, directly. past the lava,`to the metallic portion 'last burner, pass ii'om tl iat to the last lighting-wire,

The use of the insulator E' in`iixsulatinfi,r the burner possibility of such a result, and insures a prompt and perfect lighting of all the burners in the sexies.

The burner G, or` je?, is of 'the usual construction, and may be ofany ofthe dierent varieties, nnuxutictured, and is too well known to need any further der The valve o is cylindrical'in form, haring the :innulets, or annular projections k c" thereon, which serve 4as guides to keep the valves always in a proper vertical position,"aud to the lower end is iirmly secured,

by soldering, brazing,'or otherwise, the disk m, which v sho'nld be madeof soft wrought-immand forms an armature for thev magnet, while that portion oi' the valve above the disk m should be made of' brass or other non-magnetic substance.

' 'The upperend h' of the valve c is, in form, a truncated cone, madeto lit nicely the seat hiu the valvecase I.

The passage, or oriiice .1' is made through the disk n), and up through the body of the valve, to a point near its vupper end, where said passage communicates with twoiside passages *leading out at the side of the In-,figs 12,13, and 14, another modification of the valve is shown, in which the central passage i' is omitted, and small side passages i i' am made in the annular' projections k* k, for the escape of the gas.

The magnet-insulator F may be of anysnitable and in which is made a femalescrew thread, which tits properly themale-screw thread B', upon 'which the said'insulator Fis placed.

The bar "has an aperture therein, into which passes or is inserted the pipe B, said bar Dresting upouithe insulator-F, when both are in place; and the bar'D"has also the two nplights D D of soit iron at.- tached thereto, or they may hemadc solid with the bar1),aml to the top of the UprIghts-D D are attziched the pieces .C C, of sc f'tfiron, by means of screws, orin nl iy'other-propcr manner, the' inner ends 'of said pieces G protrnding'through the apertures A,

und also a short distance into the chamber" within the QQSIS case A', s short distance intervening between-tbe said The. lower pmt of the spiral .spring n rests upon the shoulderrrin the pipe B, \'vhile thenpper part.

" other end oi" the wire being connected with the other insulated post N.

'Thewh'ole 'anaugemeiitof the Icoil K, bar D', and

enclosed npxights D D, constitute a common soft-iron magnet, when the postsN N are connected wltha battel'i- But 'this feature 1I have added, viz, the extension and introduction of the poles of the magnet into-the chamber within the case A', by means ofthe ipieces G C, an`d the 'ends of said Vpieces O, which are within-4 said clnunbenfaiea' distance apart somewhatless than the diameter of the disk m, so thatwhen theclrcjixitl -oi` electricity is complete, the said pieces CC become the polesoi'the nu rnet, andthe disk, o'r armature m.

rests upon the inner ends of said pieces or poles.

The holes s s','in the lower insnlatotF, are for theA .insertion of the posts N' N., whicl x maybe firmly secured therein in any proper manner, and the holes s's, in the upper insulator E, are for the insertionoi the wires L L, which may be ofbras's or other 'suitable metal, firmly 'secured in said holes in any proper mahner; andthe platina wires, or tips D b, are secured 'at the upper' ends ofthe wiiesL L', and atalsuitabledistance apart. l

lhe lower side of the dish, or armature m, uponv the lower end ofthe valve o, is covered with av tlincoat ing, iilm, or sheet of silver or-other non-magnetic s'l`1b" stance, to prevent any liability of the said m to stick to the poies C LO of the magnet, after .the

.ciicuit'is broken, as might be the case ifsnch coating oi silver were not used, o\vingtosonre small'q'lmiitity, of electro-magnetism remaining in -the*armature m iter the circuit wasbroken Y f It is evident that the passagefthroughthe pipfe B might he of the saine size as that portion withiu'which is the spiral spring n, and, instead of the .permanent shoulder r, a small ling Amight be inserredforthe spring n to rest upon; and it is also evident that many o!" the paits might be east solid, with; great advanme as to cost and facility of manufacture, instead of being secured to each other by screwthieads,`as shown.

The pipe spring n, armature-case Avalve-case I, and valve o, I prefer to make of brass or'.other nonmagnetic subst:nice,'while the armature, 'or disk m, as well as the magnet, should be made i'sotl: iron.

Having thus 'described the construction of my invention, I will now proceed to desciibethe mode of its' operation. v

' All the' seveml puits of the apparatusfbein in# place, as shown in figs. 1, 2, and 3, and each 'en f Y the wil K, at N' N', being properly connectedwith a' battery, tliearms C C each bemme a'pole' of thema@- net, und the elastic force of' thespring n is 'overcome by the strength of the'cnnjent, or the iorce`oi`tl1e ma net, and the armature-m, secured to' the'valve o, 1s drawn down to the poles C C oi the magnet, where it remains as long as the circuit remains unbroltem This act-ion ofthe armature m, of course draws Ithe conical-shaped valve n away ii'ox n"its seat, and

communication being,y then open and uninterrupted through the pipe B, passage 1' or i', around the valvehead It', and through 'the `passages f' and'x, the gas escapes through said passages and 'out 'through this burner. v f' ,I current of electricity passesup one of the wires L,

across, over the burner, from cne platina tip b to the other, through the. jet of gas, instantly lighting it, andas long-as the circuit is kept up through the coil. K, thevalve o is held down and away from its seat by the poles O O of the'maguet, and the flow of gas continues to flow uninterruptedly to supply the ame, but the instant the circuit is broken, the valve' o flies back to-- its seat, by the elastic forceof the. spiral spring n, and the flow of gas is instantly stopped.

- As, to have this apparatus' operate successfully, some degree of delicacy or accuracy of'adjustment is necessary in the distance of the disk, orl armature m froru'the poles O of the magnet, thesame is easily accomplished by means of the nut H, as, by turning that either up or down upon the thread g, on the out side of the valve-case I, and then turning said valvecase into the armature-case A2, as far as the positionl of the nut Hiwill admit, the distance ofthe armature` m from the poles O C of the magnet is easily adjusted It'is obvious that this apparatus may be attached to any number of di'erent kinds of' gas-burners, either in buildings or stmeLs,.-.md as, by a proper connection with euch other, and with one station orbattery, by

wires,nuy number of burners may be lighted at one and the same instant, it is obvious that this apparatus is peculiarly applicable tothe lighting of nil the streetlanxps of a. large city, or any number of `burners in 'large buildings, instantaneonsly,.while it is easy of manufacture7 and not liable to any deraugemeut of parts.

Itis evident that the insulators maybe made of any suitable materials, while other suitable metals l.` The combination ot' the electromagnet, having the extension-poles G passing through a. non-magnetic substance, with the armature operating within a chamber, in the manner substantially as described.
